Thank you so much sir....l can't explain the difference between the teaching method of my teacher and you......thank you so much sir....l feel so lucky to have you as my mentor
27:48 If anyone wants to know why- O is more electronegative than C, so it pulls the bond e- towards itself and the Cs connected to Os gain partial positive charge. So, the Cs connected to these Cs gain partial negetive charge. Using this concept we can see that the middle C has more negetive character for being connected to 2 C-/=O. That is why the H connected to it are more positive which makes it easier to remove them for tautomer formation.
Sir mai apki boht respect krti hu ap jsa koi nhi prhata aap world k sbse best teacher ho sir aap plzz phle physics 11 k sare topic krwa do jldi se bcz mai bs ap pr hi dependent hu sir plzzz 11th k topic complete krwa djye plzz sir it's a request..

Sir apna mera dimag ko aaj aatho dishao se khol diya. Aaj se pehla mana itna aacha sa tautomerism kisi ko padhata hua nahi dekha.

Yes ch4 decreases conjugation on the other hand benzene ringh increases it then why the answer was other way round...was it because of h bond involvement
It's a 5M celebration.🤩 Students before 2016 : I found physics and chemistry as the hardest subject. Le students of 2020 or 2021 : I have Physicswallah.😍
16:04 here in this example hydrogen bonding does not take place because the hydrogen forming h-bond is attached to a carbon. But h-bonding is only possible when hydrogen is attached to N,O,F.
You are right but here weaker h bonding take place bcz the this carbon is attached on benzene ring which leads on polarization b/w c and h and creates a delta plus charge on h
I wonder why you provide these valuable lectures for free Really sir you will surely blessed by god for this service for us Heartfully a big THANKS for you and we all love you sir ..............😊😊😊
At @41:53 I guess the order should be D>C>A>B ... The reason for D and C is okay .... But in B there is conjugation along a EWG(phenyl) and ERG(methyl) so since the arrangement of the bond is not in favour so it will be formed least...whereas in A there is conjugation and only one ERG (methyl)..... Thank you 🙂
9:50 Sir, In A there is pi sigma lp conjugation and in B there is cross resonance which makes the molecule less stable than normal resonance So A should be more stable and high enol content.. I know Sir wouldn't see this comment after 2 years of its upload so please if anyone sees this comment reply please..
Can everyone see the difference between speed of video and speed of sound in this lecture video ? what is going on? 30:20 is very confusing due to this problem
Sir we struggle to remember whole formulas in jee preparation how it's possible to teach and remember these many topics concepts and short tricks and you are the first person who taught organic in cake walk way to me
Sir I am watching continuosly Each and Eery vedio of your's and getting clear more and more 😍thank uh so much for such a beautifull stuff 💖 And for making my bonding wid organic chem😂 Lob uh by my heat💓💓💓
Thanks a tons sir!! Initially I was struggling with tautomerism, now because of you, i am quite happy and satisfied with it. Thank you so much once again, god bless you..❤️🙏🌻
When i attempt to go to tution I have to prepare mentally that I have to capture teacher's lecture.....but when i attempt to come here I don't have to take any preparation bcz I know that if I will try my best to neglect the subject but Alakh Pandey will let me not be untaught......thats make all the difference between every teacher and you...... Thank you very much Sir 😊😊😊
I dont know why but when i start watching your videos i get ADDICTED and sometimes i feel as if i am wasting my time not doing question from diff books...any has any explaination???

Hi gya.....
Now its 13.1M
27:48 If anyone wants to know why- O is more electronegative than C, so it pulls the bond e- towards itself and the Cs connected to Os gain partial positive charge. So, the Cs connected to these Cs gain partial negetive charge. Using this concept we can see that the middle C has more negetive character for being connected to 2 C-/=O. That is why the H connected to it are more positive which makes it easier to remove them for tautomer formation.

Sir aap itna achha pdhate ho❤️or hamara ek rupe bhi nhi lgta oar school waale saal ke 40-50 hajar leke Bethe hai or kuchh nhi pdhate😔 teachers bhi achhe nhi hai sir kaas aap jese teachers school me hote🥺😔
16:50 this ques came dieectly into 2022 jee mains 26th june morning❤
41:50 order D>B>C>A hona chahiye, na ki D>C>B>A
kyoki B me aromatic ring hai na bhale hi fir usme H-Bonding na ho.
CH3 as electron withdrawing
Yes ch4 decreases conjugation on the other hand benzene ringh increases it then why the answer was other way round...was it because of h bond involvement
It's a 5M celebration.🤩
Students before 2016 : I found physics and chemistry as the hardest subject.
Le students of 2020 or 2021 : I have Physicswallah.😍
5.39M now
Now 5.81
6.74M now
9 million now
10.3 M
🎉🎉🎉wah sirji a am dropper students maja aa gya wo poorane din wah !!!
Sir...me n my phn are in love wid ur channel 💓
Tumhara network aya Kasmir main?????
@Daniel Smith padh lo
I LOVE YOU
@Shuddhasattwa Chakrabarty ohh🤭🤭😂🤣

Sir today ur shirt colour ,beginning words all were awesome 💕💕💕💕
16:04 here in this example hydrogen bonding does not take place because the hydrogen forming h-bond is attached to a carbon. But h-bonding is only possible when hydrogen is attached to N,O,F.
You are right but here weaker h bonding take place bcz the this carbon is attached on benzene ring which leads on polarization b/w c and h and creates a delta plus charge on h
I wonder why you provide these valuable lectures for free
Really sir you will surely blessed by god for this service for us
Heartfully a big THANKS for you and we all love you sir ..............😊😊😊
Best content ever on TH-cam. Thank you sir🤗🥺
Sir ur sooper explanation made me to solve many problems ..... u explain incredibly......... with lot more examples 👌👌👌👌👏👏👏👋👏😀
others advertise in the first few minutes while physics wallah utilise the first few minutes in motivating us.....thankyou alakh sir
Sir please make a short motivational video
Your motivation is too strong...
The journey continues with a strong concept ❤
Three yrs passed to this video, still effective!!
Ant story was applicable on me when I am doing IUPAC with sir but now I know there is a lot to learn
At @41:53 I guess the order should be D>C>A>B ... The reason for D and C is okay .... But in B there is conjugation along a EWG(phenyl) and ERG(methyl) so since the arrangement of the bond is not in favour so it will be formed least...whereas in A there is conjugation and only one ERG (methyl).....
Thank you 🙂
nai bhai, b me jyada conjugation hai, so b is more stable
@@adwaitT yah i too think the same
B me EWG ERG dono h but EWG ki wajah se jada conjugation h
A me kewal ERG h to wo waise b conjugation km hi krega
Organic jaisa subject
Aur aap jaise tchr
World's Best *COMBINATION *
yes!!!!!
Love from Bangladesh sir! Wonderful concept! With the help of physics wallah, I am learning Organic chemistry clearly in lockdown❣️❣️
Thanks U So Much sir
U are the best teacher in whole world ✨
FANTASTIC explanation sir.
Sir you are amazing 💞💞💞 aap lakhs me Nahi croro me ek hai🧡💛💜💞
9:50 Sir, In A there is pi sigma lp conjugation and in B there is cross resonance which makes the molecule less stable than normal resonance So A should be more stable and high enol content..
I know Sir wouldn't see this comment after 2 years of its upload so please if anyone sees this comment reply please..
😲😲😲😲 really??
Alakh sir is god of jee and neet students 🙏🙏
💯 correct
Whether you reply or not but you must have to appreciate that we (love+thank) u a lot
Can everyone see the difference between speed of video and speed of sound in this lecture video ?
what is going on?
30:20 is very confusing due to this problem
I see his videos in chemistry for concept boosting then after I get some confidence to solve mains and advance questions that are in my module 🙏🙏
Modules kharidne hai kitne mein bechoge
perfect, all doubt cleared
Alakh Sir is best 👍
starting words motivated
me so much 😍😍😍
Really sir u have clarified this topic very well now I'm feeling confident about it. ... Thank you so very much sir
Hii
@@rashilyadav7437 tera senior hu... Tameez se baat kr bhai😂😂😜
@@rashilyadav7437 oh sorry... Lekin ab tumne hi bola mai tharki hoon to behen kaise bolu junior friend?
Sir we struggle to remember whole formulas in jee preparation how it's possible to teach and remember these many topics concepts and short tricks and you are the first person who taught organic in cake walk way to me
2:45 thank you sir for opening my eyes...
If u r the best in your class, then u r in the wrong class!!!
in 41:50 sir according to points , aromaticity is most prior the option B must come on second place in order
But due to Electron repelling group...enol percentage decreases
And in option C...h-bonding hai na..isliye wo B se pehle aaya
Love u sir soo much. Love frm Kashmir.
Nd thanks so much sir
At 41:53 In option B there is one electron withdrawing group(cycle) which will reduce enol character .
So the correct order should be D>C A >B.
Electron withdrawing group increases enol character...
Watch the video carefully....
Kyaaa baat!!!!!! Shaandar lectur.. 🙏🙏🙏🙏🙏🙏
You are an amazing teacher no one can beat you
You are a best motivator
You deserve teach to Msc level student like BHU, HCU, DU, and IIT-JAM .
Sir you are good for physics and chemistry . Muje bahot Maja ata h padane me . Thank you sir.
I a m big fan of your sir
Sir u r the best teacher in this world ...hats off to u
Sir actually the third enol compound (19:00) is anti aromatic it is very unstable how it will be nearly 100% ??
2:57 lecture starts ⭐
Sir I am watching continuosly Each and Eery vedio of your's and getting clear more and more 😍thank uh so much for such a beautifull stuff 💖
And for making my bonding wid organic chem😂
Lob uh by my heat💓💓💓
Hi
17:53 sigma sigma boy sigma boy, sigma sigma boy sigma
😂🤣
Thanks a tons sir!! Initially I was struggling with tautomerism, now because of you, i am quite happy and satisfied with it.
Thank you so much once again, god bless you..❤️🙏🌻
Sir u r best ,bestestttttttt teacher in had ever seen 🧡💛🧡
that the concept i was waiting which i could even get going to coaching thnx fr all the hardwork sir
Kya English likhi hai ye
@@Ice-o-tope 😂
Thank you sir, aaj esh video k starting ki story ki need thi muje, 💙
All doubt solve after seen the alakh sir videos
U are great sir and thankU sir😊
Hii
41:30 case b ...why is hydrogen bonding not possible with the hydrogen of benzene ring and oxygen of -C(OH)=
if you go to symmetry of h bond in B ,there would be comparatively more distance b/w h and o
Option c me C=O b h jo ki jada stable h.. Aur B me kewal C= C
Best class👍
Sir, but the audio didn't sync with the video
Yes brother
Sir at 42:00
The order should be d,b,c,a
Because in op( b); we have on electron withdrawing group
But there is hydrogen bonding in c which is not in b
@@neelrekha6662 but priority is of aromaticity at first
Ya I am with ankur
Very helpful isomerism series..❤️❤️👍❤️❤️
Your all lectures are awesome.. And learning plus ➕
sir I am preparing for jee 2023 .Thank you very much sir 🙏
Sir ....u are the best ....the true teacher....thank you sir!!
Thnku sir....... 😊😊😊😊
Hi harshita
Yarr kuch toh reply kr diya kro
@@kishansingh4939 kuuu...?
Acha km se km yeh toh bta do ki neet ki preparation kr rhi ho yaa iit ki aur biomentor se pdhai yaa coaching join kiya hai
i am sure neet ki preparation kr rhi ho
When i attempt to go to tution I have to prepare mentally that I have to capture teacher's lecture.....but when i attempt to come here I don't have to take any preparation bcz I know that if I will try my best to neglect the subject but Alakh Pandey will let me not be untaught......thats make all the difference between every teacher and you......
Thank you very much Sir 😊😊😊
Sir in the first example in the structure A) tautomer there is conjiction by lonepair-sigma-db then why its not stable
Sir u are amazing teacher Keep it up 🥰🥰

Pranam 💕💕💖💖❤🙏😍🤩
I dont know why but when i start watching your videos i get ADDICTED and sometimes i feel as if i am wasting my time not doing question from diff books...any has any explaination???
